At this point the reader has reached the end of the file.

So you can't read any more using that same reader you
need to create a new reader. (Or reset the old one, but
I don't think that's possible)
But why are you using a DictReader when you immediately
convert the data into a list? Why not use the standard
reader which returns tuples. Or why not just use the dicts
that you have - usually that leads to more intuitive
and reliable code since you access the data by name
rather than column number.
